An Efficient Load Balancing Technology in CDN

The existing load balancing technology in the content distribution network (CDN) only emphasizes even load distribution among servers, and it does not make the best of network topological information and the historical information of file accessed, so user request can not get timely response. To solve the above problem, this paper presents a load balancing a algorithm based on the Distributed binning strategy. This algorithm can make full use of network topological information and file access history as well as server load information, analyzing the popularity of files with the access history of the clusters of clients from the servers, efficiently finishing distribution and routing of the high popularity files among servers so that users can closely get their requested content, relieve the congestion situation in the Internet and then enhance the speed of response when they accessing Websites.
